How I create text editor in a couple of days using vibe coding For the past couple of days, I've been vibe coding a fully functional text editor using Rust (yes, yet another text editor). <br />So, I thought it would be interesting to share some thoughts, the lea...

Fala pessoal, resolvi criar uma PoC e ver como essa parada de vibe coding com agente poderia funcionar e o quanto funcionaria.
Com isso resolvi criar um editor de texto do zero, e nesse blog post tento explorar todo meu aprendizado e alguns problemas do caminho.

Does this diagram help? It uses the React Performance Tracks to explain what React is doing, and what you'll see when you use the tracks:

React’s ViewTransition Element The Canary version of React has a special component for ViewTransitions. Does it help?

@chriscoyier.net maybe it's only me, but your document.startViewTransition() + React doesn't work well for me, on both latest Chrome/Firefox

Surprisingly, both browsers fail in different ways
The <ViewTransition> React comp works well in both cases

Está no ar a página do apoia-se para quem quiser se juntar!

O apoia-se possibilita contribuições menores, então isso deixa a campanha mais acessível aos interessados.

Tenho também uma nova categoria de contribuição (vai lá ver!)

AGENTS.md outperforms skills in our agent evals - Vercel A compressed 8KB docs index in AGENTS.md achieved 100% on Next.js 16 API evals. Skills maxed at 79%. Here's what we learned and how to set it up.

This doesn't surprise me at all, I had realized that plenty of "skills" or "mcp servers" are glorified docs query functions. A well structured index of files seems easier for an LLM to work with vercel.com/blog/agents-...

My weird experience with buying a domain through @bsky.app:

In late 2024, we set-up the bsky account for the React Vienna Meetup. We didn’t have a domain yet so I bought @reactvienna.com through bsky.

The domain expired 1 year later. I’ve set up email forwarding but never received anything...

Atenção operadores de PDS e desenvolvedores de aplicativos que consomem do Firehose ou Jetstream do Bluesky 'bsky.network'.

O Firehose será atualizado na próxima terça-feira, podendo ter interrupções breves na transmissão de dados.

Recomendado ler o comunicado completo abaixo.

Bluesky's been systematically surrendering to platform thinking ever since the Charlie Kirk shooting and mod rampage; the need for diversified infrastructure remains unabated

Reading through this is both fascinating and horrifying.

It's hard not to start feeling like working with React is like being in a relationship with a partner who's gonna blow up at you if you say things the wrong way or with the wrong tone of voice and expects you to read their mind.

Por que todo desenvolvedor precisa entender CI/CD desde cedo? CI/CD não é só para DevOps Engineers. Descubra por que entender integração e entrega contínuas é uma habilidade essencial para desenvolvedores que querem entregar valor com qualidade e velocidade.

Do you like a free tool? Send money.

Do you use a tool at work? Convince your employer to sponsor it. Stop marketing OSS as free stuff to your employer, and treat it as a cost for the company.

You only endanger the OSS project, if you don't give something in return.

Que o modelo open source é quebrado e a indústria é parasitária. Os grandes nomes que conseguirem ser comprados vão ser, os pequenos vão continuar ferrados

a @novelo.social.br será engavetada.

o @felgus.dev e eu há um tempo estamos um tanto quanto desanimados com a gestão do bluesky e os impactos no ATproto e vimos que podemos gastar energia e tempo em algo que esteja mais alinhado com o que acreditamos e onde sem dúvidas nos sentimos melhor. 💜
